I found (two) of those small solar chargers that you can strap on the back of your pack or lay out in the sun at camp to charge things like your phone or other small devices. When I got home I looked them up on the internet and they run between $120- $160 bucks. Would you believe I got them for $2 bucks apiece??? Wow, I\'m on cloud nine! No more worries about running out of juice in the back country! :dance2:
